Speciiication forming part of' LettersPatentfNo. [S9-209, dated April 3,1877; application filed Y I' f" I February 24, 1877 Figure l of thedrawings is a representationof a central .vertical-section of my supplyink-Wells; and Figs. 2, 3, and 4are detailviews of the same. Fig. 5 is aside View (part sec tional) thereof.

The object of this invention is'toxprovide Vconvenient devicesforfilling inkstands from a protected reservoir, and` emptying` said standsinto the same. This object is effected by the combination, with an inkwell or reservoir, of aA screw-.operated piston or follower and a systemof pipes 4leading to the different inkstands, as hereinafter set forth.

In the accompanying drawings, A designatesan ink well or reservoir,which is upright and cylindrical in form, having its upper end open.Said reservoir Ais inclosed in a protecting jacket or casing, B, whichrises above it and supports a cover, B. Said cover is centrallyperforated at b, and has also smaller perforations b' b on oppositesides thereof. O designates a metal block dovetailed into the top ofsaid cover, as shown in Fig. 3, and eX- tending across the same. Saidblock is screwu tapped at c and perforated at o c', to correspond withsaid perforations b b' b'.

D designates a screw-threaded rod, which Works through saidscrew-threaded central perforation c, and is operated by turning amilled head or disk, D1,.xed on its upper end. Said cover B and block Gare secured to said casing B by means of milled nuts d d, which arescrewed home upon screw-threaded rods or bolts d', that pass upwardthrough perforations b and c', above described. The lower ends of saidrods are secured to said casing B.

The lower end of adjusting-rod D is provided with a piston or follower,E, which works up and down in ink well or reservoir A,'and

is constructed as hereinafter described. When the said piston orfollower is depressed by the action of said screw-threaded adjusting-rodit .forces the ink slowly' out of said reservoir g through an opening,a., at the bottom thereof, into a vertical passage or tube, F, Fig. 5,

which may be formed in one piece with reservoir A, or separately, aspreferred. From said passage F the ink flows into a distributing pipe,(Eq-connected to said passage by elbowcoupling G. Said distributing-pipeis pro; vided Witha number of small branch pipes, H H,4 as shown in Fig.l, which are, preferably, vertical,'and pass up through the respect-'ive desks'to ink-stands I. Each one of said v.inkstand's has a smallhorizontal ingress-pas' jsage, i, which'communicates with the upper endof its tube H. This communication may -be cut off or allowed to remain,at pleasure, by .turning a small cock, J,which has near its' lower end away, j. Said cock works in avertical cylindrical seat or space in saidinkstand. Where only a single desk is to be supplied with ink a form ofinkstand without cock may be used, similar to that shown in Fig. 5.Several distributing-pipes, Gr, may be used instead of one, when such anarrangement is more convenient.

The piston or follower E consists of a bottom disk, E1, preferably ofglass, a sectional upper plate, E2, and a series of interposed layers ofrubber or other packing, E, which serve to keep the contact of saidfollower with inkwell Aair-tight.' Said' sectional upper plate E2 isprovided with an upward tubularvextension, e, and dividedvertically.Said sectional tubulaiextension is screw-threaded on the outside, andheld together by a screw-tapped `closed at top and bottom. In saidchamber sets a small cylinder or fixed collar, D2,on the lower end ofscrew-threaded rod D, also a similar collar or head, e3, on the upperend of a shank, E3, attached to disk El. The

above-described construction of said piston or follower makes it as firmas if manufactured in a single piece, while Vallowing all its parts tobe readily separated for convenience in cleansing or other purposes.

When the said piston or follower is drawn up by the operation ofscrew-threaded rod D,

rrrcn.

the ink is drawn back into reservoir A by the vacuum thus created andthe pressure of the external air. This completely emptiesdistributingpipe G and so many ot' the inkstands- I as are then incommunication therewith. The casing B and top B', being of materialwhich does not conduct heat well, will then protect the ink fromfreezing.

By'using this invention the accumulation of sediment in inkstands isalmost entirely prevented, as they are frequently emptied, and

" the escaping current through their bottom openings cleanses them ofall impurities. Water may also be forced in and out for this latterpurpose by operating piston E. This invention also economizes time infilling and emptying the inkstands, and withdraws the ink from allcontact with the atmosphere, whereby it is speedily deteriorated onaccount of evaporation and the deposition of dust, &c.

My inkwe1l is especially suited to be used in school-rooms, or whereverelse many persons are engaged in using ink at the same time. Theindependent cock-connection of the differ` ent inkstands to thedistributing-pipe makes it possible to' fill anyone or more` of saidstands without filling the remainder, or to leave one or more still fullafter school-hours or office-hours, when the others have been emptied.

rlhe parts of said apparatus which come incontact with the ink may bemade of any substance which will not be injured thereby. Passage Fshould be iuclosed within casing B. L

What I claim as new, and desire to secure v by Letters Patent, is- Yy 1. The combination of an ink-reservoir, with a follower workin gtherein, and a distributingpipe leading to several different inkstands,substantially as and for the purpose set' forth.

2. Non-conducting casing B and head B', in combination withink-reservoir A and vertical passage F, substantially as and for thepurpose set forth.

3. The combination of screw-tapped block C and screw-threaded rod D withpiston or follower E, well A, tube F, and distributingpipe G,substantially as and for the purpose set forth. l

4. TheJ combination of distributing-pipe Gr, with branch pipesH,inkstands I, having sepa- 'rate cocks J passage F, reservoir A, andpiston E, substantially as and for the purpose set forth. l

5. The combination of screw-threaded rod D, having xed collar D2, withsectional upper piece E2, clamping collar or nut e1, packing E4, landdisk El, having shank E3, with a collar xed on its upper end,substantially as andforlthe purpose set fort In testimony that I claimthe above I have hereuntosubscribed my name in the presence of twowitnesses.
